Abstract

PURPOSE: To compensate the lowering of reproducing output simply and well at a low-tape speed time by switching the number of coil windings of a reproducing head while interlocking with switching of the tape speed.
CONSTITUTION: Switch 7 to switch motor control circuit 6 and switch 10 to switch the tap position of coil 9 of reproducing head 8 are interlocked with each other. When the tape speed is lower, the number of windings of coil 9 of head 8 is increased. Consequently, even in case of a low tape speed, reproducing output from head 8 is not lowered, and the lowering of reproducing output is compensated without gain adjustment of a reproducing amplifier, etc. As a result, the lowering of reproducing output can be compensated simply and well according to the tape speed.
